THE CANADIAN ENTOMOLOGIST. 83 



A NEW COCCID FROM TEXAS. 



BY T. D. A. COCKERELL, NEW MEXICO AGR. EXP. STATION. 



Aulacaspis texensis, n. sp. — 9 scale circular, 173 mm. diameter, very 

 slightly convex, dull brownish-gray or sepia-brown, becoming transparent 

 at the edges ; sometimes entirely whitish. Exuviae exposed, sepia-brown, 

 not far from central, ist skin to one side of 2nd, but wholly on it, with 

 some white secretion extending over the centre of the 2nd. 



9 alive, plump, dull pale greenish-orange. When dead and dry 



dark yellowish-brown, remaining so when boiled in soda. Outline 



circular, pygidial portion striated ; anal orifice rather small, as far behind 



\ level of caudolateral groups of glands as they are behind cephalolateral. 



»A marginal row of 3 or 4 longitudinally elongated pores ; and a sub- 

 marginal row of pores, the two caudad longitudinally elongate, the 3 

 cephalad small and round ; 5 groups of ventral glands, caudolaterals ro, 

 cephalolaterals about 16, median about 8. Median lobes wide apart, 

 with a slight prominence between them bearing a pair of small spines. 

 Median lobes oblique, much as in A. bromelice, but the long inner slope 

 convex, with 5 very distinct serrations, counting the one which forms the 

 tip ; outer short margin with one serration. Immediately outside each 

 median lobe, and touching it, is a spine-like plate, its tip about or hardly 

 on a level with the tip of the lobe. Then comes a very small and low, 

 strongly bifid 2nd lobe, then a spine, then a rather large spine-like plate, 

 then a very low and broad trifid lobe (one might almost as well say 3 

 serrations on the margin), then a spine, then a spine-like plate, then two 

 serrations, and a very rudimentary third (sometimes all three obscure), 

 then another spine-like plate, and after a short interval another, then 

 after a short interval a pointed prominence followed by a notch, then 3 

 m spine-like plates at rather long intervals. 



 ^ scale I mm. long, white, tricarinate, but the lateral carin?e rather 



" feeble ; exuviae very pale ochreous. The $ scales occur in patches on 

 _ the leaves, much as in Chionaspis exercitata, Green. 



K i7a<^.— San Antonio, Texas, Nov. 27th, 1895, on both sides of 



™ leaves oi Sophora secundiflora. [C. H. T. Townsend.] 



The species was first collected by Mr. Schwarz; and afterwards 

 Messrs. Howard, Schwarz, and Townsend found it very abundant near 

 San Antonio. The plant was determined by Mr. Coville. This is the 

 first native North American Aulacaspis.
